missing DISP button on newer cameras

Newer cameras do not have a separate display button. But the DISP button is an important CHDK button. I think we need an uniform replacement. My suggestion - the video button. The video button is not used in any CHDK alt mode function.

For some cameras is the DOWN button also defined as DISP button. With such cameras you have to try to use the layout editor (Pixel stepwidth & move down are the same, that's funny!).

Probably because nobody has found the time or interest to work on it. That happens some times - there are not many people actively working on CHDK who have the skills and knowledge to do this and they get busy with other things.

The solution with the record button seems to be fine. Is there already a ticket for this issue?

CHDK does not have a ticket system, or a schedule, or even much of a plan going forward. It's just a small group of volunteers who work on things that seem important or interesting to themselves.

The solution used with the S100 looks fairly easy to implement. If you'd like to test it, I'll need your camera model & firmware version.

Really ? That now seems strange. When I looked at it closer, I think that you also need to change the keymap[] in kbd.c so that the bit map for the "Video" button is assigned to the "Display" button. The #define only changes the text field used in the annoying pop-up help box.
